While Virginia auto insurance requires drivers to have a minimum amount of liability coverage, there are a number of other add-on policies that can be good to have. Investopedia offers some advice on what add-ons drivers should consider when purchasing auto insurance.

Gap insurance is protection in the event that a driver owes more money on the vehicle than the insurance company is willing to pay after an accident. By evaluating the car's worth before the accident, they then determine how much the insurer may pay if the car is totaled. The source notes that leased or financed vehicles may cause the same issue, but gap insurance provides funds for the difference.

Roadside assistance provides mobile repair and towing services to policyholders in case their car breaks down on the road. Investopedia notes that having this additional insurance policy can be good for drivers who frequently travel on their own or with children.

Personal Injury Protection insurance is another worthy addition in many situations. It can cover many different expenses such as medical expenses, funeral costs and deductibles.
